Varicose veins in the lower extremities are the most common disease in vascular surgery, and they eventually develop into foot ulcers, commonly known as old rotten feet, which are very painful for patients. The main treatment method – traditional surgery – leaves many large and small surgical scars on the whole lower limb, and it is always the goal of surgeons to reduce the size of the surgical incision and meet the aesthetic needs of patients. Based on our mastery of minimally invasive techniques, our vascular surgery department has taken a different approach by carrying out minimally invasive surgery without the use of instruments. By improving the traditional surgery, the varicose vein mass stripping is changed to point stripping, which greatly reduces the surgical incision and improves the minimally invasive surgery, which reduces the patient’s pain and burden at the same time, and is welcomed by the majority of patients. Compared with the traditional surgery, our surgery is minimally invasive and beautiful; compared with the original minimally invasive technology, our surgery is cheaper and the surgical effect is really effective without the help of expensive instruments, saving several thousand dollars in one surgery, which is very practical; the hospitalization time is short, generally the hospitalization time is about 5 days, the recovery is fast, and the patient can go down to the ground on the day of surgery; the scar range is small, the scar left on the lower leg is only 0.4-0.6cm long It has a certain cosmetic effect and can meet the needs of female patients in particular.
